Target fish: trout
Hook: 6 - 8
Tail: 2 goose biots, alternatively natural red hackles fibers
Underbody: lead wire at wish
Body: red schwannundaze

Notes: the ecdyonurus is one of the most present mayfly nymphs in european trout streams. This pattern can imitate this genus rather effectively. Often gave me the biggest trout of the pool.
